The waiting time for initiating an inquiry is 7 days for an airmail item and 30 days for a surface mail piece. Any U.S. sender or the addressee can initiate inquiries concerning standard international airmail and parcel post. These inquiries must be filed within one year from the day following the date of mailing. The overseas postal administration will pursue the inquiry with the U.S. Postal Service.
Service is available in both English and Spanish.
At this time, the Inquiry Center is unable to handle e-mail inquiries. However, if your inquiry is filed sooner than 7 days after the date of the mailing or later than 90 days after the date of the mailing, delivery information may not be available. In addition, if an inquiry that is filed later than 90 days after the date of the mailing indicates loss, damage, or rifling, the mailer will not be eligible for refund of postage or an indemnity claim since the time limit for filing has been exceeded.
