Telecheck primarily operates within the United States, focusing on facilitating check processing and payment verification for domestic transactions. It specializes in services that support merchants in ensuring the legitimacy of checks presented for payment within the U.S. As a result, Telecheck may not be equipped to handle international transactions or checks from outside the United States. Merchants seeking to conduct international transactions or to process checks from foreign banks should consider alternative payment methods or services that are specifically designed for cross-border transactions. It is advisable to check the Telecheck website for the most current information regarding their services, as there may be updates or changes in their offerings.
