The evaluation is based on widely accepted market standards for QQ number valuation, considering factors like length, digit patterns, and special digits. However, actual market value may vary due to supply-demand dynamics and personal preferences, so results are for reference only.

Value depends not only on digit count but also on digit patterns, special sequences, and arrangement rules. For example, numbers like 888, 666, or 12345 (straight sequences) are far more valuable than ordinary numbers of the same length.

The intrinsic value is determined by immutable features like digit count and pattern. However, you can enhance the account’s overall worth by staying active, increasing your QQ level, or subscribing to VIP services.

The certificate visually presents the QQ number’s estimated value and serves as a reference. You can save or share it with friends or use it as a valuation reference during trades. Note: it is for reference only and has no legal standing.
