Which Address to Use When Mailing Someone at Comal County Jail (P.O. Box vs. Street Address)

Regular inmate mail, like letters and cards, goes to the jail's P.O. Box. Packages and legal mail go to the street address: 3000 IH 35 South, New Braunfels, TX 78130. The jail routes these through separate intake processes, so sending to the wrong address can mean delays or misrouted mail.

Sending a standard letter or card? Use the Comal County Jail P.O. Box address. On the envelope, include the inmate's first and last name along with their SO number so staff can match it to the right person.

• ✓ Inmate’s first and last name
• ✓ SPN/SO number
• ✓ Comal County Jail, TX
• ✓ P.O. Box 16120
• ✓ Jonesboro, AR 72401

Packages and legal mail need the jail's street address, not the P.O. Box. Include the inmate's first and last name and SO number, and send it to Comal County Jail at 3000 IH 35 South, New Braunfels, TX 78130.

1. Confirm what you’re sending: If it’s a package or legal mail, use the street address (3000 IH 35 South, New Braunfels, TX 78130).
2. Add the inmate’s name and SPN/SO number: Put both on the shipping label so it can be matched to the right person.
3. Use a carrier that delivers to street addresses: Packages should be addressed for delivery to the jail’s physical location.
4. Identify legal mail clearly: If you are sending legal mail, keep it separated and labeled as legal mail on the outside of the envelope.

Every piece of mail needs a complete return address: your first and last name plus a full mailing address. If the jail can't identify who sent it, they'll return it.

• ✓ Your first and last name
• ✓ Your full street address (or P.O. Box)
• ✓ City, state, ZIP code

The SPN (also called an SO number) is how mailroom staff match mail to the correct inmate. For publications specifically, Comal County Jail requires the SPN on the shipping label. No SPN? The item gets returned.

Most mail problems come down to a few fixable mistakes: using the P.O. Box when the item should go to the street address (or vice versa), leaving off a return address, or forgetting the inmate's SPN/SO number. A quick double-check before you seal the envelope or print the label can save you days of waiting.

• ✓ Regular letter or card: addressed to the P.O. Box
• ✓ Package or legal mail: addressed to 3000 IH 35 South, New Braunfels, TX 78130
• ✓ Inmate’s first and last name is included
• ✓ Inmate’s SPN/SO number is included (especially on shipping labels)
• ✓ Your return address includes your first and last name and complete address
• ✓ Legal mail is clearly marked as legal mail on the outside (when applicable)

1. Read the return details: Look for what was missing or incorrect, such as an incomplete return address or no SPN/SO number.
2. Fix the label or envelope: Add your first and last name plus a complete return address, and add the inmate’s SPN/SO number where it’s easy to see.
3. Resend using the right address type: Regular letters go to the P.O. Box, and packages or legal mail go to the street address.
