numbers.suffix_collision
The proposed series range overlaps with existing number_inventory rows.
numbers.suffix_collision is returned when an admin series inventory generation request specifies a start/end suffix range that would produce E.164 numbers already present in the number_inventory table. The platform rejects the entire batch rather than creating a partial set.
The suffix range overlaps with existing inventory rows. This can happen when generating inventory for a prefix that was partially generated before.
Adjust the start and end suffix values to a non-overlapping range. Review existing inventory for the prefix to identify available gaps.
