# Businesses can call back without your number

Businesses often say "we'll call you back." If you didn't want to give out your own number, the call used to stall there.

Now each call without a callback number gets its own 4-digit extension on our line, (469) 966-0062. The assistant gives the business that number and the extension.

When they call back, they press or say the extension and leave a message. Your agent sees it in `get_call` and `account`, and it shows on your [account page](/account). A voicemail the assistant leaves includes the extension too.

Want them to reach you directly instead? Give your agent a callback number and the assistant passes it on. More in [caller ID and callbacks](/guides/ai-call-caller-id-and-callbacks).
