An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this American Express phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like American Express staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.
The least busy time to call
The least busy day to call American Express is Monday. The most busy day to call is Tuesday. Again, this is based on a sample of 8,124 calls made with our AI-powered, web-based phone in the last 90 days.
The shortest wait on hold
We measured the shortest hold times to be on Friday. The longest wait in the queue on average occurs on Tuesday.
The best time to call
In summation, the best day to call American Express is Monday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that American Express staffs the call center well on Monday.
