OTPs not coming to my number set on my account

Your original phone number is no longer a trusted number for your Apple ID, even though it appears on your account.

Apple only sends verification codes to trusted numbers, not all numbers listed.

If your number was downgraded, removed, blocked, or marked unreliable by Apple’s system, it will stop receiving OTPs.

This is why:

• You DO receive OTPs on the new number
• You NO LONGER receive OTPs on the original number
• The original number still shows on your Apple ID, but Apple is not using it for verification

I believe you mean what Apple calls a "verification code".

Make sure the number is still listed as a trusted number. The below is based on the section "About trusted phone numbers and trusted devices" in the article Two-factor authentication for Apple Account - Apple Support

To see, add, or change your trusted phone numbers use one of these methods:

● On your iPhone, iPad, or iPod touch: Go to Settings > your name > Sign-In & Security. Tap Two-Factor Authentication, tap Edit (above the list of trusted phone numbers), then enter your device passcode when prompted. Add or remove the number, then tap Done.

● On a Mac computer choose Apple menu  > System Settings (or System Preferences), then click your name (or Apple ID). Click Sign-In & Security, then add or remove a trusted phone number.

● Using a web browser:

1) Go to https://account.apple.com and sign in.

2) Follow Account Security options until you find one letting you change trusted numbers,

3) Click "+" to add a new number (you may be required to verify this number).

4) If you wish to remove an old number, click "-" next to the number.

If you still have issues, contact Apple. While what is posted in another reply about Apple no longer trusting specific numbers, I have never seen that mentioned on this forum before and the poster does not provide any references to that being an Apple procedure. Do you see any kind of error message when you try your first number?
