BBB ratings represent the BBB's opinion of how the business is likely to interact with its customers. The BBB rating is based on information BBB is able to obtain about the business, including complaints received from the public. BBB seeks and uses information directly from businesses and from public data sources.

BBB assigns ratings from A+ (highest) to F (lowest). In some cases, BBB will not rate the business (indicated by an NR, or "No Rating") for reasons that include insufficient information about a business or ongoing review/update of the business's file.

BBB Business Profiles generally explain the most significant factors that raise or lower a business's rating.

BBB ratings are not a guarantee of a business's reliability or performance. BBB recommends that consumers consider a business's BBB rating in addition to all other available information about the business. (from https://www.bbb.org/overview-of-bbb-ratings)
