Why Provide a CSR with Your Port Request

A Customer Service Record (CSR) is a document from your current provider that proves you own the phone number you are porting.

Available on: All plans


What a CSR does

  • Verifies your name, address, and account number match carrier records
  • Confirms the numbers listed on your port request are active on your account
  • Provides the exact details the receiving carrier needs to process the transfer

Why it matters

Submitting a CSR alongside your Letter of Authorization (LOA) significantly improves approval likelihood and prevents delays. Without a CSR, mismatches between your LOA and carrier records are the most common cause of porting rejections.


How to get a CSR

Contact your current phone provider and request a Customer Service Record. Most carriers provide this within 1–2 business days.

Note: Toll-free carriers typically do not provide CSRs. In that case, enter your own account information directly on the LOA along with your account number.
