This is in the spirit of the What is a Word/Phrase™ series started by JLee with Number version puzzles.
If a number conforms to a special rule, I call it an Encoding Number™.
Use the following examples below to find the rule.
$$ % set Title text. (spaces around the text ARE important; do not remove.) % increase Pad value only if your entries are longer than the title bar. % \def\Pad{\P{0.0}} \def\Title{\textbf{ Encoding }} % \def\S#1#2{\Space{#1}{20px}{#2px}}\def\P#1{\V{#1em}}\def\V#1{\S{#1}{9}} \def\T{\Title\textbf{Numbers}^{\;\!™}\Pad}\def\NT{\Pad\textbf{Not}\T\ }\displaystyle \smash{\lower{29px}\bbox[yellow]{\phantom{\rlap{rubio.2019.05.15}\S{6px}{0} \begin{array}{cc}\Pad\T&\NT\\\end{array}}}}\atop\def\V#1{\S{#1}{5}} \begin{array}{|c|c|}\hline\Pad\T&\NT\\\hline % \text{ 9 }&\text{ 7 }\\ \hline \text{ 10 }&\text{ 8 }\\ \hline \text{ 60 }&\text{ 58 }\\ \hline \text{ 95 }&\text{ 93 }\\ \hline \text{ 193 }&\text{ 191 }\\ \hline \text{ 315 }&\text{ 313 }\\ \hline \text{ 1,034 }&\text{ 1,032 }\\ \hline \text{ 2,194 }&\text{ 2,192 }\\ \hline \text{ 5,979 }&\text{ 5,977 }\\ \hline \text{ 16,466 }&\text{ 16,464 }\\ \hline \end{array}$$
