Question: I am looking to publish an audiobook on ACX, and I am 13 years old. **Is there any age restriction on publishing an audiobook on ACX?** For example, during registration, it asks me if I hold a US tax ID for the payments from ACX.

Answer: 
You must be 18 to publish on ACX.

But you can probably convince a parent/guardian to publish for you.

Amazon will also publish audiobooks, but you will still need a parent/guardian to publish for you since you are under 18.
18 (or the legal age of majority) is the minimum. Minors aren’t able to enter contracts, which is required for publishing.

There are a number of [steps required for publishing](https://www.acx.com/help/legal-contracts/200485430), and the first is [opening an account](https://www.acx.com/help/account-holder-agreement/201481940): “To open an account on ACX, you must be a resident of the United States, the United Kingdom, Canada or the Republic of Ireland and be at least 18 years old or the legal age of majority in the jurisdiction in which you reside.”

I believe you can have your parent/guardian get your book published as an audiobook for you by giving them the [“Authority to Enter into this Agreement”](https://www.acx.com/help/ZXZ8Q2SFT6NQA2E). Still, I suggest contacting ACX support to ensure there are no legal problems.
