# How to Send Photos to San Diego County Jails > How to send photos to San Diego County jails: the Mail Processing Center address in Santee, booking number, photo tips and how to keep mail from being returned. Published October 10, 2026 in Mail & Facility Rules To send photos to someone in a San Diego County jail, mail them to the Sheriff's **Mail Processing Center, 451 Riverview Parkway, Building C, Santee, CA 92071**, with the person's name, booking number and facility. Since September 1, 2022, mail addressed directly to six of the county's detention facilities has been rejected and returned to the sender. That one address covers the whole San Diego County jail system, from San Diego Central Jail downtown to Vista and Las Colinas. Below is the format to use, how to find the booking number, the photo rules and what to do so your envelope isn't sent back. ## Mailing address for photos The San Diego County Sheriff's Office says mail must include **the person's name, booking number and facility**, as well as **the sender's name and return address**. Its [Sending Mail and Packages page](https://www.sdsheriff.gov/bureaus/detention-services-bureau/sending-mail-and-packages) gives one central address for all of its jails: ``` [Full name] [Booking Number] [Facility name] Mail Processing Center 451 Riverview Parkway, Building C Santee, CA 92071 ``` Replace [Facility name] with the jail your loved one is in, such as San Diego Central Jail or Vista Detention Facility. The sheriff's office is clear that mail sent directly to six of its detention facilities is **rejected and returned to the sender**, so use the Mail Processing Center even if you know the jail's street address. The Sheriff's Office runs several jails. Our facility pages show the latest details we have for each: - [San Diego Central Jail](https://inmatepics.com/facilities/california/san-diego-central-jail) (downtown San Diego) - [George F. Bailey Detention Facility](https://inmatepics.com/facilities/california/george-f-bailey-detention-facility) (San Diego) - [Las Colinas Detention and Reentry Facility](https://inmatepics.com/facilities/california/las-colinas-detention-and-reentry-facility) (Santee) - [Vista Detention Facility](https://inmatepics.com/facilities/california/vista-detention-facility) (Vista) - South Bay Detention Facility (Chula Vista) - East Mesa Reentry Facility and Facility 8 Detention Facility (San Diego) San Diego also has federal and immigration facilities, and a state prison, that the Sheriff doesn't run and that have their own mail rules. You'll find them on our [California page](https://inmatepics.com/facilities/california). ## The ID number you need The sheriff's office asks for the person's **booking number** on all mail. If you don't know it, the sheriff's office points families to its **Who's In Jail** search on the Sheriff's website. Tips for using it: - Search with your loved one's full legal name. - Note the booking number and the facility listed for them, since you'll need both. - Check again right before you mail. People move between San Diego jails and are released often.

All mail entering a jail is **opened, inspected and searched for contraband**. The sheriff's public mail page doesn't list photo sizes or a per-envelope count, and it links to its detention policies for the detailed list of unacceptable items. Rules can change, so we keep the details we use on our facility pages. These are the basics: - **Size:** Standard 4x6 prints. - **Number:** Our facility pages list up to 10 photos per envelope. We split bigger orders into more envelopes. - **Content:** No nudity or sexual content, gang signs, weapons, drugs or money. - **Plain prints.** Send standard photo prints, not instant photos, with nothing glued, taped or stuck on. Everyday moments make the best pictures: the kids after school, a family barbecue, the dog, a new apartment, a sunset at the beach. ## What your loved one receives The sheriff's office says all mail is opened and searched for contraband, and that **the writing is scanned** for safety and security reasons. Its public mail page doesn't say that photos are replaced with copies or shown only on a tablet. Before you pay, our checkout shows what your loved one will receive at their San Diego facility, based on what we have on file, and we update our facility pages as rules change. ## Step by step 1. **Look up your loved one** on Who's In Jail and write down their booking number and facility. 2. **Choose your photos.** Clear, appropriate pictures of family, friends, pets and home. 3. **Crop them to 4x6.** 4. **Address the envelope** with their name and booking number, the facility name, then Mail Processing Center, 451 Riverview Parkway, Building C, Santee, CA 92071. 5. **Add your name and return address.** The sheriff's office requires it. 6. **Mail it** by U.S. Postal Service.
