Under the Dutch system, coverage is based not only on work, but also on residence.
Most persons who reside in the Netherlands will have residence-based coverage up to
age 65 which is the Dutch retirement age. Thus, when issuing a coverage record for
a person younger than 65, the Dutch often assume that the claimant will continue to have residence-based coverage up to the 65th birthday.
Since it is obviously impossible for the Dutch to establish a full and exact coverage
record prior to age 65, the Dutch refer to these as “provisional” records. The Dutch will follow up with a non-provisional record only if the provisional
record is later found to be in error.
