Unable to receive SMS verification code required to create Meta for Developers account.
I am attempting to register for a Meta for Developers account at developers.facebook.com to build an Instagram Graph API integration. The registration flow requires phone number verification via SMS, but no verification code is ever delivered to my phone.
Environment:
- Country: South Korea
- Phone: regular carrier-issued mobile number (not VoIP, not virtual)
- The same number receives SMS from all other services (banks, Google, Apple, etc.) without issue
- Personal Facebook account is active and in good standing; this phone number is already linked to it
- No existing Meta for Developers account associated with this number
Symptoms:
- The verification screen displays "Code sent" but no SMS arrives
- Waited well beyond the stated delivery window on each attempt
- After repeated requests, the system rate-limits further attempts
- Issue persists across multiple browsers (Chrome, Safari, Firefox), incognito mode, and different network connections (home Wi-Fi, mobile data, different IP)
Troubleshooting already attempted:
1. Re-added phone number to Accounts Center two-factor authentication (SMS option) — no SMS received
2. Attempted WhatsApp verification path via Accounts Center — failed
3. Waited 24+ hours between attempt batches to avoid rate-limit lockouts
4. Tried different devices (desktop and mobile)
5. Verified phone number is correctly entered with +82 country code
6. Confirmed carrier (Korean major carrier) is not blocking short-code SMS
7. Checked spam/blocked-sender settings on the phone — clear
Data loss / abuse: None. This is a pre-account-creation issue. I have not lost data or experienced abuse; I am blocked from creating the account in the first place.
Impact: I cannot proceed with building the planned Instagram Graph API integration until phone verification is resolved.
Request: Please manually verify my phone number on Meta's side, or provide an alternative verification path (email-based, ID document, etc.).
