NL 10608.115 Do I Need to Include a Servicing Office Address?
A. Field office notices
By law, every Title II and Title XVI notice issued by a field office must include the address and telephone number of the local servicing office.
B. Notices issued by other components
When the office issuing the notice is not the servicing office, you must include a phone number and the address of the servicing office in the referral paragraph or in another section of the notice. You may show the national toll-free 800 number 1-800-772-1213 instead of the servicing office telephone number.
See NL 10609.115C for more information about the appearance of the servicing office address in the referral paragraph.
