@jessie_jones_godlover I worked at D&B for 8 years, but it’s been a while so some things could have changed slightly.
As a general rule, larger companies, like a Walmart or Home Depot are much more likely to report to D&B than smaller companies. You can always self-report, although that will cost you money. Ignore the advice above about personal credit being the same as your business credit. That’s just wrong. It could be that your business credit is so weak that you have to rely on personal credit or guarantees (especially while your business is young), but they’re definitely separate beasts.
Working out a strategy to start building your business credit early can definitely pay off after a few years when you’re able to get vehicles, materials, loans, etc based on your company’s credit. But who you use can/should really depend on the industry your in. There’s lots of office/hardware supply companies, website hosts, virtual office spaces, etc that specifically pitch that they report to D&B.
Maybe most important, you need to pay “on terms”. The key to a strong business credit score is having other business trust you to pay them over time (such as on 30 day terms) and then they report that you actually paid on time (or early).
In terms of a list of specific companies that report, that information is purposely kept close to the vest. Most big companies don’t want their B2B customers to know they report, so there’s no big list out there. And finally, very few, if any, business credit cards report to D&B, unless, of course, you start miss payments. They’re way more likely yo report negative payment activity than anything positive.
