Does the LLC need a DUNS#?

[Ruth Lacuzong]

Hello Everyone! Great to virtual meet you. I just created my LLC and open a business bank account to finally start my real estate investing journey. I am very new and have been following on social media on various real estate investors to learn this past year, so now I'm jumping right in to take action  :-) 

Does a single-member LLC need to have a DUNS#? I've been reading a lot about building credit within your business, and many said DUNS# is helpful, but does that also apply to businesses where my LLC is created to just buy/hold/sell properties?

A little about me: my overall goal is to build passive income and generational wealth for my family. Looking into starting with wholesale first, then use that money to do rehab/flip, then buy/hold/1031residential homes to duplex to apartments.
