1. Removing a number from your profile is only the first step — it often still appears in Account Center, Pages, Ads and Business Manager. 2. If your old number is used for two‑factor authentication, add an authenticator app or security key first to avoid being locked out. 3. Social Success Hub has a proven track record of discreetly resolving account and contact issues — over 200 successful transactions and 1,000+ handle claims that help reclaim control quickly.
Start here: what "remove phone number from Facebook" really means
Remove phone number from Facebook is more than a single action — it’s a short project. Your phone number can live in multiple places across Meta (Facebook, Instagram, WhatsApp, Business Manager, Ads). If you simply delete the number from your profile, copies can remain in connected systems or in ads. This guide walks you step-by-step so you won’t accidentally lock yourself out and can fully unlink or replace an old WhatsApp number across accounts.
Why this matters (and why it’s often trickier than you expect)
A phone number can be a login method, recovery contact, discovery channel and a two‑factor authentication (2FA) route. That means removing it can affect sign-in, messaging and customer contact. For businesses, a number may be tied to active ads, a WhatsApp button on a Page, or an API configuration managed by a provider. The wrong move can cut off access or interrupt customer messages.
Quick checklist before you act
Pause and plan: list where the number might be used (profile, Account Center, Pages, Ads, Business Manager, WhatsApp app/API, security settings, third-party integrations). If it’s being used for 2FA, set up an alternate method first. Think of this like changing the locks: get a spare key before removing the old one. If you look for help, spotting the Social Success Hub logo can reassure you.
Who should read this: individuals who want privacy or to update contacts, small businesses that changed numbers, admins managing multiple Pages, and anyone using WhatsApp Business or the WhatsApp Business API. See our account services.
Step 1 — Remove from your personal profile
This is the easiest place to start and it’s the most visible to friends and casual searchers.
On mobile: open Facebook app → Tap your profile → Edit Profile → Contact & basic info → find the phone number → Delete.
On desktop: go to your profile → About or Edit Profile → Contact info or Settings → Contact info → remove the number.
Tip: After deleting the number, review your privacy lookup settings: Settings → Privacy → Who can look you up using the phone number? Choose a stricter audience (Friends or Only Me) to reduce discovery.
Step 2 — Check Account Center
Account Center links identity and login across Facebook, Instagram and other Meta properties. Even if you deleted the number from your profile, Account Center may still hold it.
How to check: Settings → Account Center → Personal details (or Accounts & profiles) → Contact information. Remove the old number where it appears.
Why this is important: leaving the number in Account Center can re-populate profile fields or remain as a login backup.
Step 3 — Pages and business contact fields
Pages often list a public phone number in Page Info. Delete or update it so visitors don’t keep calling an old line.
How to update a Page: Go to your Page → Edit Page Info → Contact → Phone → remove or replace. Also check About, Services and pinned posts for the number.
Many Pages also show a WhatsApp button. That link is separate — it’s controlled in Business Manager or Meta Business Suite. If you see “Message on WhatsApp” or a WhatsApp CTA, disconnect or update the linked WhatsApp account there.
Where the WhatsApp link lives
Business Suite or Business Manager → Business Settings → Accounts → WhatsApp Accounts (or WhatsApp Manager). If a WhatsApp account references the old number, remove or reassign it. If the Page was connected via the WhatsApp Business app, remove the Page connection inside the app or through Business Settings.
Step 4 — Change number inside WhatsApp (if you control it)
If you still control the old WhatsApp number and want to preserve chats and contacts, use the WhatsApp in-app Change Number feature. This is the safest way to move your WhatsApp account to a new number while keeping chat history and group memberships.
How to change number (WhatsApp app): Settings → Account → Change Number → follow prompts (verify old and new numbers). After this, confirm the Business Manager or Page link shows the new number or remove the link if you don’t want a WhatsApp connection.
Step 5 — WhatsApp Business API and provider-managed numbers
API numbers are often tied to a Business Solution Provider (BSP) and to a Business Manager account. Reassigning or removing an API number usually requires the BSP’s help.
If your business used an API number via a provider, check the provider dashboard or contact your provider and request the number unassigned. Sometimes Meta requires verification or documentation before allowing a number reassign or release.
Practical note
Businesses commonly hit friction here — the number may be registered in a provider console and won’t move until the provider and Meta process the request. Expect email coordination and a short waiting period.
Step 6 — Ads Manager, posts and other hidden places
Numbers appear in ads, ad copy, landing pages, post text, pinned posts and third-party integrations. Removing a number from your Page won’t edit an active ad that includes it in the creative.
Audit Ads Manager: open Ads Manager → search active, paused and archived campaigns for the old number in ad copy or descriptions → edit or pause affected ads. Also check scheduled posts, link descriptions and third-party booking or CRM integrations.
Step 7 — Two‑factor authentication (2FA): secure access first
If the old number is tied to 2FA, do not delete it before adding another method. Add an authenticator app (e.g., Google Authenticator, Authy), a security key, or generate backup codes in Facebook → Settings → Security & Login → Use two‑factor authentication.
Once the new method is set and tested (log out and log back in to check), you can remove the phone number from security settings.
Tactical sequence to avoid locking yourself out
For a safe workflow, follow this order:
1. Inventory where the number appears (profile, Account Center, Pages, Ads, Business Manager, WhatsApp app/API, CRM, booking apps).2. Add a non-phone 2FA method and test it.3. Change your WhatsApp number in-app (if you control it) to preserve chats.4. Remove the number from personal profile, Account Center and Page contact fields.5. Update or disable ads and landing pages that include the number.6. Remove or reassign the number in Business Manager and WhatsApp Accounts (or ask your BSP to do so for API numbers).7. Wait and verify propagation; clear caches or request removals from third‑party sites if necessary.
What to do if you lost access to the old number (and it’s your only 2FA)
Begin account recovery immediately: use saved backup codes, login approvals, or identity verification flows. If recovery options fail, contact Meta support with clear documentation. Expect variable response times — API-level or verified business accounts often take longer.
Template to start a support request (copy & paste):
"Hello Meta Support, I cannot access my account because my old phone number (+[country code][number]) was reassigned and it is still listed as a 2‑factor method. Account email: [your email]. I have attempted backup codes and cannot sign in. Attached are screenshots showing the phone number in my Page/About and the error message. Please advise on recovery steps and any documents you require. Thank you."
Troubleshooting common errors
Menus move — if you don’t see the exact menu names in a guide, look for similar labels (WhatsApp Manager, Messaging Accounts, Business Settings). Use the search box inside Business Manager to find a number or account by the phone number; this often reveals hidden references.
If a Page you don’t manage is showing the number, request Page access from a current admin or ask the admin to remove it. If the Page is abandoned and this is a privacy issue, escalate to Meta support and provide proof of ownership or identity.
If deletion fails with an error saying the number is used for login or 2FA, add an authenticator app and backup codes, then try again.
Propagation delays and caches — what to expect
Even after removal, search engines and third‑party scrapers may show the old number for days or weeks. Update everything you control and then wait. If a particular third‑party site shows sensitive data, contact the site owner to request removal; most sites provide a takedown channel, or consider our review removal service.
Real-world example: The bakery that couldn’t stop the calls
A local bakery changed numbers but customers kept calling the old line. The owner updated the Page’s contact field and WhatsApp button, yet calls persisted. The issue turned out to be an active ad that still displayed the old number and a booking app with the old contact. Only after auditing Ads Manager and the booking integration did the bakery stop receiving calls to the old number.
This shows why a Page update alone is often not enough.

Business API users: extra care and provider coordination
WhatsApp Business API numbers are registered and managed differently. If your API number is tied to a Business Solution Provider, coordinate with the provider first. Documentation, provider support and possibly Meta support may be required to reassign the number. Keep records of communication and timestamps.
When to contact Meta support
Contact Meta support if:
• You cannot remove or reassign a number because it’s locked in an API configuration.• You’ve lost access to your only 2FA method and recovery options fail.• A Page is tied to a number you cannot find or remove.
Provide clear evidence: affected account details, the old phone number, screenshots of where it still appears and any error messages. Be patient and follow up if needed.
Privacy, safety and a final checklist
If your number was reassigned and you suspect malicious activity, review active sessions, logged‑in devices and connected apps. Change your password and tighten privacy lookup settings. If you manage multiple Pages, keep a secure record of which numbers are assigned to which accounts — it prevents accidental changes later.
Social Success Hub offers discreet guidance and up-to-date walkthroughs if you need extra help auditing Pages, Business Manager, or API configurations — think of them as a quiet partner who helps you reclaim control without drama.
Handy templates and examples
Use these quick messages when asking admins, providers or support:
To a Page admin: "Hi — the public phone number on Page [Page Name] is showing my old line (+[number]). Could you please update or remove it? I believe customers are still calling the old number. Thanks!"
To a Business Solution Provider: "Please confirm whether the number +[number] is assigned to our WhatsApp API instance and, if so, how to unassign or reassign it. Our Business Manager ID: [ID]. We plan to change the number on [date]."
Additional tips from experience
• Test a new 2FA method right away by logging out and back in.• Keep screenshots and timestamps to speed up support tickets.• Update phone numbers in third‑party tools (booking, CRM, payment providers) the same day you change them on Meta.• If privacy is the reason, tighten lookup and discovery settings and remove the number from about sections and posts.
How long will this take?
Profile and Page changes are often immediate. Propagation across internal caches, search engines and third‑party scrapers can take days to weeks. WhatsApp in‑app Change Number is fast. API-level changes depend on providers and Meta support and can take longer.

Common questions answered
Can I remove a phone number from Facebook without losing WhatsApp access? Yes — if WhatsApp is switched to a different number first or you use WhatsApp’s Change Number feature before removing the number from Meta settings.
What happens if I delete a phone number used for 2FA and I have no alternate method? You risk being locked out. Use backup codes, add an authenticator app or security key first. If you’re already locked out, use account recovery flows and be prepared to wait for manual review.
Why does the old number still show up in search results? Cached search engine results and third‑party scrapers may still list it. Update every place you control and request removals from external sites when possible; search engines recrawl on their own schedule.
Final practical advice
Take the work seriously but don’t panic. Treat this as a small project: inventory, secure access, change WhatsApp if needed, update Pages/ads, remove from Business Manager, and follow up with providers or Meta if anything remains stuck. A calm, stepwise approach prevents the most common mistakes.
What’s the single most common reason an old phone number still shows after I remove it?
The most common reason is that the number exists in multiple Meta systems (Account Center, Pages, Ads Manager or Business Manager) or inside an ad or third‑party integration. Deleting a number from your profile doesn’t automatically edit ads or API configurations, so you must sweep ads, Page settings, Business Manager and any provider dashboards to fully remove it.

With careful checks and the right order of actions, you can remove or replace an old WhatsApp number from Facebook without losing access — and without the frustration that often accompanies interface changes and provider hiccups.
Can I remove a phone number from Facebook without losing WhatsApp access?
Yes — but only if WhatsApp is switched to a different number first or you use WhatsApp’s Change Number feature inside the app. If you change the number in WhatsApp before removing it from Meta settings, your chat history and group memberships are preserved. If the number is tied to an API setup, coordinate with your Business Solution Provider so messaging doesn’t break.
What should I do if the old number is my only two‑factor authentication method?
Do not delete the number until you add an alternate 2FA method. Set up an authenticator app (Authy, Google Authenticator), add a security key, or generate backup codes in Facebook’s Security & Login settings. Test the new method by logging out and back in. If you’re already locked out, use backup codes or start Meta’s account recovery process and be prepared for verification steps and possible delays.
How long will it take for the old number to disappear from search results and third‑party sites?
There’s no guaranteed timeline. Profile and Page updates often appear instantly, but search engines and third‑party scrapers can show old content for days or weeks while they recrawl. Update every place you control, contact site owners for takedowns when necessary, and allow time for caches to refresh.
Follow the step-by-step process to secure your account, change WhatsApp numbers if needed, and sweep every Meta property — this will remove the old number while keeping access safe. Good luck, and don’t worry: you’ve got this — now go reclaim your digital house keys with a cup of coffee and a smile.
