I am trying to delete a number but am blocked by this error.

”Cannot delete phone number with active SMS A2P 10DLC application, please delete the SMS application first.”

Since the number is stuck in “review” I don’t have the option to remove the SMS capability. I am stuck paying for a number that is not going to be used. I need someone to delete this number and stop the billing!

The number ID is +19562768936  
My workspace ID is org\_R9jWuUx6KK1l0QGE

I understand your frustration with being unable to delete a phone number that has an SMS application stuck in review. This is a known issue that requires direct support intervention.[(1)](https://discord.com/channels/1186424376300679209/1423494115433119796)

When a phone number has verification or SMS applications in review status, you cannot delete the number yourself through the standard API or dashboard.[(1)](https://discord.com/channels/1186424376300679209/1423494115433119796) The error message you’re seeing—“Cannot delete phone number with active SMS A2P 10DLC application”—prevents deletion until the application is resolved.[(1)](https://discord.com/channels/1186424376300679209/1423494115433119796)

**What you need to do:**

The support team can manually delete numbers that are blocked by pending verifications.[(1)](https://discord.com/channels/1186424376300679209/1423494115433119796) They will need to escalate this to resolve the stuck review status and remove the number from your account to stop billing.[(1)](https://discord.com/channels/1186424376300679209/1423494115433119796)[(2)](https://community.retellai.com/t/branded-call-verified-phone-and-sms-stuck-in-review/306)

**Typical timeline:** While SMS applications typically process within 1-2 weeks, applications stuck in review require manual intervention from the support team.[(2)](https://community.retellai.com/t/branded-call-verified-phone-and-sms-stuck-in-review/306)
