# How to move your number from Grasshopper to Onyx Phone

Grasshopper business numbers. You set a 4-digit Primary PIN in the Grasshopper app.

## What you'll need from Grasshopper

- **Account number:** Usually your main Grasshopper number, 10 digits. It's the Customer ID under Settings, Account info.
- **PIN:** A 4-digit Primary PIN that you set yourself. Set it just before you start the move.
- **Name and address:** exactly as Grasshopper has them on your account. Copy them from a recent bill.
- **A recent bill:** a PDF or a photo from the last 30 days.

## Get your PIN

1. In the Grasshopper app, open the menu, then Settings, then Account information.
2. Choose Primary PIN and set a new 4-digit PIN.

## Good to know

- The account must be active with nothing owed.
- If the PIN option isn't there, call Grasshopper support and ask for your port-out PIN.
- Keep your Grasshopper service until the move is done, or the number can be lost.

## Then move it to Onyx Phone

1. Start your free trial. You get a temporary local number right away, so you can make and take calls today.
2. Forward your current number to the temporary one if you like (most landlines: dial *72 and the number), so customers reach you here during the move.
3. In Onyx Phone, open Lines, then Begin a port, enter the details above, and attach the bill. Moving a number is free on every plan.
4. Sign the letter of authorization we email you. Nothing starts until it's signed.
5. The carriers confirm a date, usually 3 to 7 business days after you sign. On port day your number replaces the temporary one, and calls you place show it.
6. The temporary number keeps ringing your line for 30 more days, so anyone you gave it to still gets through, then it's released.

Texting registration doesn't come with the number. US carriers approve each business that texts, so register in Onyx Phone when you start the move; approval usually takes one to two weeks, and calling works meanwhile.
