“Chris, was super professional and kind to me and the other patrons in the San Marcos Postal Annex. He was a one-man show that was super nice despite the busy lobby and even helped a man who requested assistance with his box.
Great service is rare these days and it was super great to see such a helpful professional young man! Thank you, Chris!”
“I have been using PostalAnnex at 1637 E Valley Pkwy in Escondido for over 25 years, and they continue to provide outstanding service every single time. Whether I need shipping, a mailbox, copies, notarization, or even house keys made, they are always professional, knowledgeable, and eager to help.
What I love most is that they offer virtually every shipping service imaginable, including domestic and international shipping to destinations all over the world. The staff consistently go above and beyond to make sure everything is handled correctly and efficiently.
In a world where great customer service is becoming harder to find, the team at PostalAnnex stands out. They are friendly, reliable, and truly care about their customers. After more than two decades of doing business with them, I can confidently say they are one of the best businesses in Escondido.
Thank you for 25 years of exceptional service I highly recommend PostalAnnex to anyone looking for dependable shipping and business services!”
“I am at this location at least once a week for the last 5 years, and I receive nothing but excellent service. They are all knowledgeable and are willing to be helpful. I have been to the Mira Mesa location, where they are not as knowledgeable or as willing to help out. I have visited many UPS stores throughout the county, and hands down this location have the best customer service and know what they are doing.”

“This shop reminds me of the good old days when customer service was king. The man in charge is efficient and helpful. I had a return label issue and he was able to find a solution so I could send my package. He is a pleasure to speak with and you can tell he cares about his customers. Highly recommend his services!”
“Won’t use any other UPS. I’ve been a regular at this store for the past two years and the whole team here is always so helpful and goes above and beyond. Eric and Ali are efficient and friendly- no matter how busy it is.”
“I'm so grateful I found these guys. I needed to ship legal documents to Canada, and I wanted to make sure it was done right and not for some obscene amount of money (like some other places charge). Leo was a huge help for me - both over the phone and in person. Thank you so much!”
“Dina went up and above when my Military clients needed a power of attorney… Time was of the essence and she was more than happy to accommodate our request. Then when I had to call Dina and let her know that additional documentation was needed quickly… once again she stepped up to keep us in Compliance even if it meant keeping her way past closing time! Had this been a different Notary there is a good chance My clients would’ve missed their opportunity to complete their task. It definitely pays to find someone that you trust, who is a team player and knows the job isn’t done until everything is complete.”
“This shipping store is awesome! Both Escondido locations and staffed by knowledgeable fast working people who can help you with anything shipping related! They also have a notary you can use on demand! Great locally owned and operated business I love to support ❤️”
“So grateful for the owners and all the amazing services they have offered over the years to us. Hands down the best customer service. I feel fortunate to have such a wonderful mail service provider.”
“This Postal Annex is great!! The staff is so friendly and I enjoy everytime I go check my mail and talk to the employees! The owner is a very nice and funny man! They are the best, I recommended if looking for a Postal Annex!”
“Yesterday June 8, 2026 I went to this store to ship 3 boxes and I didn’t have labels printed because my printer didn’t work so I asked Mr. Mike if he could print the labels for me and he was so helpful and friendly he made me feel a valued customer. I had a bad experience at the other UPS store in San Marcos they weren’t helpful at all so I did not go back there to ship my boxes and will never use that store to ship anything or use any of their services.
Mr Mike and his staff are very friendly they make you feel welcome and valued customer I will surely comeback to their store for their services for shipping, printing etc. highly recommend 100% for their top notch service!”
“⭐️⭐️⭐️⭐️ Best UPS Store! They take care of business in record time!
Thanks very much,
Clarence Jasmagy, jasmagy|)esign, Patents and Trademarks”
“I've been a patron for 3 years now. In the beginning it was a bit rough on the edges, but I can honestly say that they have turned their customer service right around and are super friendly, not to mention some of the hardest working people I know here in town. They take pride in their work day in and day out and I am thankful they have such a dedicated team. Thank you UPS San Marcos!”
