Although the FDCPA does not specifically say how many times
collectors can call, the Federal Trade Commission (FTC) has published their
interpretation of the FDCPA. The FTC says debt collectors' calls must be for a
productive purpose such as verifying information, following up on a previous
conversation and so forth. They cannot keep calling you for the sole purpose of
demanding payment; doing so is harassment.
It's important to note that creditors are exempt from this
federal requirement, however your State Laws
may prohibit this activity.
