Wonderful place with friendly, super helpful employees. The exact opposite of Everett's Hoyt post office.


I work in a neighboring city, and live in Mukilteo. Consequently, depending on my schedule I access three different post office locations in Snohomish County. The Mukilteo Post Office staff is absolutely my favorite.They are friendly, helpful, and never make me feel like my questions are silly or unreasonable. They genuinely make me feel welcome, and it seems like they enjoy their work with customers. Thank you!


I absolutely love this post office. The lobby being 24 hours is perfect for Snohomish county, unlike the Hoyt Ave location. The tellers are always friendly, even when the patrons are not. I've always had great, helpful service. I will definitely continue to use this location.
