The NCUA Registrations

The NCUA regulations have three provisions affecting advertising. Since all three are relatively simple, and consist of only one paragraph, the simplest thing to do is to reprint them. The first two provisions apply to all federally insured credit unions, regardless of whether the credit unions are federally or state chartered.
No insured credit union may use any advertising (which includes print, electronic, or broadcast media, displays and signs, stationery, and other promotional material) or make any representation which is inaccurate or deceptive in any particular, or which in any way misrepresents its services, contracts, or financial condition, or which violates the requirements of Sec. 707.8 of this subchapter, if applicable. This provision does not prohibit an insured credit union from using a trade name or a name other than its official charter name in advertising or signage, so long as it uses its official charter name in communications with NCUA and for share certificates or certificates of deposit, signature cards, loan agreements, account statements, checks, drafts and other legal documents. [12 CFR 740.2]

Any advertising that mentions share or savings account insurance provided by a party other than the NCUA must clearly explain the type and amount of such insurance and the identity of the carrier and must avoid any statement or implication that the carrier is affiliated with the NCUA or the federal government. [121 CFR 740.3]

The third provision applies only to federally chartered credit unions.
A federal credit union shall accurately represent the terms and conditions of its share, share draft, and share certificate accounts in all advertising...whether written or oral. [12 CFR 701.35(b)]

As you can see, the NCUA basically requires that your advertisements be accurate and not misleading.

The reference to “§707.8 of this subchapter” in the first quoted paragraph above is to the NCUA Truth-in-Savings regulation. The paragraph is saying that a credit union may not violate the advertising requirements of the Truth-in-Savings regulation, if the regulation applies.
