Client Setup & Billing

Since September 2021, all new clients must complete Form AG-257 to receive a customer number with Texas A&M AgriLife Extension Service. If you’ve used other AgriLife services before, include your existing customer number on the TPDDL form.

Form AG-257 Department Contact: Courtney Overby

We cannot begin sample processing without a customer number or prepayment. If you prefer not to complete Form AG-257 (e.g., homeowners or those unwilling to provide SSN), you may pre-pay by check (blue or black ink only) made out to Texas AgriLife Extension Service. Note: Pre-payment limits analysis to the requested service(s) only.
