369 in Mobile Number

With Pythagorean numerology, no number is anti any other number. There is some to be said about degree of compatibility, which I'll address in a moment.

The calculated foundation number of a mobile number is much more useful for interpreting than the individual digits. With the Any Number calculator, you can find any number's foundation number. It also has a graph representing the various strengths of the individual digits within the number.

The energies represented by a number are compatible with some other number energies and incompatible with others. Compatibility of Number Energy has a chart with the various compatibilities. There is no "anti-", but degrees of compatibility and incompatibility.

As you will see with the chart, the numbers 3 and 9 are compatible. The numbers 3 and 6 are slightly incompatible. As an aside, the numbers 3 and 4 are even more incompatible than 3 and 6.

Perhaps you are using a different numerology practice than I do. If that is the case, it may be prudent to consult with a numerologist who practices the numerology you are comfortable with.
