If an IRS office has issued you a Certificate of Registry or a
Letter of Registration that is still in effect for an activity, you
are not required to reapply for registration for that activity
unless notified to do so. However, see Reregistration for
Fuel Activities below. To apply for another activity or to
cancel a registration, you must contact the IRS office in
which you are registered.
CB,

submitted with an application changes. This includes, but
is not limited to, address changes or changes in business

Reregistration for fuel activities. You must reregister with
the IRS if there is a change of more than 50% of the
ownership of a registrant and you are registered for activity
letters K, M, S, W, Y, AB, AF, or NB. In this instance, a
change in ownership means that after a transaction (or
series of transactions), more than 50% change of the
ownership interests in, or assets of, a registrant are held by
persons other than persons who held more than 50% of
such interests or assets before the transaction (or series of
transactions). Reregistration does not apply to companies
whose stock is regularly traded on an established
securities market. If you fail to reregister as required, see
Penalty above.
To reregister, send a newly completed Form 637 to the
address under Where To Apply above. On line 1d, enter
your current registration number. The IRS will revoke the
