license in the GMRS will normally have a term of ten years from the date of grant or renewal, and may be renewed pursuant to the

procedures of FCC. To obtain a GMRS operator license, you need FCC Form 605 & 159, we suggest visiting the FCC website at

https://www.fcc.gov/wireless/support/fcc-form-605, which includes necessary instructions. More questions about the license application,

please contact the FCC at 1-888-225-5322 or go to the FCC's website: http://www.fcc.gov.

According to FCC rules, any individual who holds an individual license may allow his or her immediate family members to operate his or her

GMRS station or stations. Immediate family members are the licensee's spouse, children, grandchildren, stepchildren, parents,

grandparents, stepparents, brothers, sisters, aunts, uncles, nieces, nephews, and in-laws.
