# Get Registration Details

GET https://api.agentphone.ai/v1/register

Retrieve the content of your submitted A2P 10DLC registration.

Returns the brand identity and campaign content exactly as it was
submitted (business info, description, use case, sample messages, opt-in
consent flow, opt-in screenshot URL) so you can review what carriers are
reviewing. Internal registry ids, vendor names, and processing state are
never exposed; the coarse `stage` mirrors GET /v1/register/status. The
EIN is returned as its last 4 digits only.

Like the status endpoint, this resolves to a sub-account when the
registration lives on one (the default for POST /v1/register) — either
automatically when there's exactly one, or via the X-Sub-Account-Id
header.
