After a WHOLE bunch of research, we came out with the best answer possible; NOBODY KNOWS!
There are attorneys that say you do need to include LLC in your logo.
However, there are attorneys who believe that using LLC in your logo is NOT necessary.
The attorneys who believe that you NEED to include LLC in your logo understand as follows:
You should not leave any doubt for the consumers to figure out if your company is an LLC or not.
For that reason, you should include LLC in your logo.
On the other hand, we mentioned that there are attorneys who believe that it is NOT necessary to add LLC to your business logo.
They believe as follows:
A logo is only an extension of your business’s trade name. It is not a direct representation of your business.
For this reason, you do NOT need to add LLC to your logo.
What we think it really boils down to, is whether or not your logo is a legal representation or not.
If that’s the case, then in most situations your logo is NOT a legal representation of your business.
Instead, a logo is a BRANDING representation of your company. Branding departments do not need legal recognition.
For this reason, we do NOT recommend you to include LLC in your logo.
In fact, including LLC in your logo could even be BAD for you.
It may ruin the imagery of your logo, in terms of its design.
This is the case for branding purposes.
HOWEVER, this does NOT apply to invoices, contracts, leases, legal records, tax returns, letterhead, or any legal documentation.
