Here\u2019s a simple way to check if a taxpayer identification number (TIN) is valid or not<\/strong>.<\/p>\n

If you\u2019re a business owner or a self-employed individual in the gig economy, you must know Form W-9 and Form 1099-NEC<\/a>.<\/p>\n

While Form W-9 is used to obtain the TIN\/EIN from the independent contractor (also synonymous with vendors or freelancers), Form 1099-NEC is used to report the payee\u2019s TIN along with their legal name.<\/p>\n

Now, if you work with a couple of independent contractors, it can be relatively easy to validate their TINs per the official records. This can be done through the online TIN Match system offered by the IRS.<\/p>\n

But it can get complicated as you onboard more vendors and as the volume of TINs, you have to validate increases.<\/p>\n

This is when a bulk TIN match and real-time TIN matching come in handy.<\/p>\n

The following will discuss the process of TIN matching and how to check if a TIN is valid.<\/p>\n

What is a TIN?<\/h2>\n

A TIN (taxpayer identification number) is a legal identification attribute assigned by the IRS and\/or Social Security Administration. It identifies individuals and entities uniquely.<\/p>\n

In this context, EIN (employer identification number) is also a TIN. SSN is also a type of TIN.<\/p>\n

A TIN is a unique combination of letters and numbers assigned to an entity or individual.<\/p>\n

No two entities have the same TIN\/legal name combination.<\/p>\n
