Moving from Attentive

If your customers text a toll-free or local number at Attentive, you can bring that number to Chargezen and keep the conversations going on the number they know. Start by finding out what kind of number you send from.

Many Attentive programs send from a short code, a 5- or 6-digit number. A short code can't move to Chargezen, whether it's shared or dedicated to your brand. A toll-free or local number that's yours can. Ask Attentive which kind you have before you start.

Chargezen moves US (+1) local and toll-free numbers that can send texts. Short codes (5 or 6 digits) can't move. A local number needs an approved 10DLC registration in Chargezen first, so it can text the moment it arrives. Type the number into Bring your number and Chargezen tells you whether it can move, and why not if it can't, before you fill in anything else.

Attentive's help center has no public article on moving a number away from Attentive (checked October 18, 2026). Its short code transfer article covers short codes, which Chargezen can't take. Ask your Attentive customer success manager or Attentive support for:

• Whether the number can be released to you, and that it's a toll-free or local number rather than a short code.
• A recent invoice as a PDF from the last 30 days, showing the number if possible.
• The business name and address on the account, exactly as Attentive has them.
• For a local number: the account number, port-out PIN and billing phone number.
• For a toll-free number: how you'll see a text sent to that number, because Chargezen texts it a code to confirm it's yours.

When you submit the move, you pick a port date at least 5 business days out. Chargezen books the earliest date the carriers allow on or after it, and the confirmed date (the FOC date) shows on the number's row under SMS numbers. Carriers set the exact time.

• Toll-free numbers: texting usually moves about 3 business days after you confirm the code, before the port date. The row shows Texting live. On the port date, calls move too.
• Local numbers: calls and texts move together on the port date, and the number joins your approved 10DLC campaign.
• When the move is finished, the row shows Moved. If you chose Concierge answers calls, the number is ready in Chargezen Voice for you to activate.
• If the move is sent back, the row shows Needs attention with the reason. Click Fix, correct the step it opens and click Resubmit move.

In Chargezen, go to Concierge > Deploy > Channels, click Chargezen SMS and, under SMS numbers, click Bring your number. Here is what to enter from Attentive at each step. The full walkthrough is in Bring your number.
