How to Call TIAW


TIAW has adopted the OneBox virtual answering service to provide direct assistance to our members and other callers. You may use the Click to Call button or call directly using the numbers below.

Our new toll-free number is 888.712.5200 for all North American callers

Our international local number is +1.202.351.6839

The OneBox attendant answers during the hours of 8 a.m. to 7 p.m. Monday through Friday and 9 a.m. to 1 p.m. Saturday (Eastern Time). If OneBox hears a fax tone, the fax is transcribed to email and sent to the appropriate person.  

If the person you are calling is not able to answer, you will have the opportunity to leave a voicemail message.
