How to find your account number and PIN to port your fax number

The most common reason a port stalls is a missing or incorrect account number or PIN from your current provider. Here is exactly what we need, and where to find it.

What every port needs

• The exact fax number you are bringing over.
• Your current fax provider's name.
• Your account number with that provider.
• Your account PIN, passcode, or port-out PIN.
• The billing phone number and service address on that account.
• A recent bill or invoice (PDF or photo, under 1 MB).

The name, address, and account number must match your current provider's records exactly — a mismatch is the number one cause of port rejections.

Where to find them, by provider

• eFax: Your account number and service address are on your eFax invoice and in your eFax account profile. eFax does not issue a customer "PIN" — we handle the carrier-to-carrier request for you. Heads up: some numbers eFax assigned to you (rather than ones you originally ported in) can carry a one-time release fee; we will tell you if that applies.
• MetroFax / MyFax / eVoice: Sign in to your account portal for the account number and service address. These carriers often say a port-out PIN is "generated automatically when the details match," so the key is making sure the account number, name, and address you give us are exactly what is on file.
• magicJack: Get your account number from my.magicJack.com, and confirm it with magicJack support (1-844-866-2442) since the portal sometimes shows the wrong one. Your PIN is your portal password — reset it to an 8-digit number first. The account must be active and paid; an "account number mismatch" rejection is usually a ZIP+4 issue.
• RingCentral / Nextiva / Vonage / 8x8: The account number and port-out PIN are in the admin portal under account or billing settings. Some require you to set a port-out PIN before requesting the transfer.
• A local phone company (landline fax): Use the Billing Telephone Number (BTN) and account number from a recent bill. If fax shares a multi-line account, tell us — sometimes the whole account has to move together.

Can't find your PIN? Send us what you have. In many cases we can complete the port with just the account number, name, and address. Submit your request on the Phone Numbers page, or start at the porting signup page.
