Find out who actually owns the account.

A collector, servicer, and debt owner are not always the same company. That affects what proof you should ask for.

Possible role: Private collection contractor and third-party collection agency

Coast describes collecting for federal and state agencies, colleges, and local governments. IRS and Treasury sources list it as a private agency that may contact people about government-assigned debts. That makes it a contractor collecting on the government's behalf — it doesn't own the debt.

For IRS tax debts, confirm that you received IRS Notice CP40 before responding to Coast.
For college, university, state, local, or federal nontax debts, confirm which school, agency, municipality, utility, or federal program placed the account.
