When you have a query that you seek answers for, please do your due diligence and check with the appropriate licensing and notarial commission issuing agencies FIRST; not just one single For-Profit business entity.
=> It’s YOUR business reputation that’s on the proverbial line.
The National Notary Association [NNA] is a For-Profit BUSINESS entity.
If you perform a Search here on Notary Café, you’ll find many threads with posts from members who have successfully completed the NNA certification, but who certainly don’t sense they came away with a good, solid foundation of knowledge. So, those members advise taking another certification course to supplement the information.
Many have posed these valid queries (and many more) over the years:
“Why doesn’t the NNA work to get our Notary Fees increased?”
“Why doesn’t the NNA fight against Remote Online Notarization [RON]?”
“Why does the NNA charge such HIGH PRICES for their services & supplies?”
“Why did the NNA Hotline give me incorrect information?”
It appears the term “association” within their name is a misnomer.
If you choose to rely on the NNA, that’s your choice. Please do keep in mind that it’s prudent for you to seek out several sources for answers to your questions, not just one single For-Profit business entity.
