Amazon.com has served a cumulative 6.2 million customers as of the end of 1998.

True: Amazon's 1998 shareholder letter or annual report/10-K states that cumulative customers served by year-end 1998 were 6.2 million (any figure that rounds to 6.2 million). Mostly true: the official figure is 6.0–6.4 million, or 6.2 million at a slightly different cut-off date in late 1998 or early 1999. Mixed: the figure is 5.5–6.9 million. Mostly false: the 6.2 million figure measures something else (for example active customers or accounts in a different period) and is presented as cumulative customers. False: Amazon's records show a cumulative figure clearly different from 6.2 million (outside 5.5–6.9 million).

3. E3 Amazon.com Announces Financial Results for Fourth Quarter 1998 Amazon.com, Inc. · 26 January 1999 Own record

   “Amazon.com announced that cumulative customer accounts increased by more than 1.7 million during the fourth quarter to over 6.2 million at December 31, 1998, an increase of over 300 percent from 1.5 million customer accounts at December 31, 1997.”

Amazon's Form 10-K for fiscal 1998 says the company had approximately 6.2 million cumulative customer accounts as of December 31, 1998 (E1). The 1998 annual report filed with the SEC says the same: cumulative customer accounts grew from 1.5 million at the end of 1997 to 6.2 million at the end of 1998 (E2). The Q4 1998 earnings release gives a matching figure of over 6.2 million at December 31, 1998 (E3). The filings give the 6.2 million figure as cumulative customer accounts at year-end 1998 [E1][E2][E3], which the report treats as matching the cumulative figure the criteria require for 'true'.
