=== Alphanumeric systems ===
{{see also|Gematria|Isopsephy}}
There are various numerology systems which assign numerical value to the letters of an [[alphabet]]. Examples include the [[Abjad numerals]] in [[Arabic]], [[Hebrew numerals]], [[Armenian numerals]], and [[Greek numerals]]. The practice within [[Jewish]] tradition of assigning mystical meaning to words based on their numerical values, and on connections between words of equal value, is known as ''gematria''.{{sfn|Stratton-Kent|1988}}

The [[Mandaeism|Mandaean]] number alphasyllabary is also used for numerology ([[Mandaic language|Mandaic]]: ''gmaṭ aria''). The ''[[Book of the Zodiac]]'' is an important [[Mandaean text]] on numerology.{{sfn|Häberl|2023}}

===Pythagorean method===
In the Pythagorean method (which uses a kind of place-value for number-letter attributions, as does the ancient Hebrew and Greek systems), the letters of the modern [[Latin alphabet]] are assigned numerical values 1 through 9.{{sfn|Christie|2005|pp=10–11}}

=== Agrippan method ===

[[Heinrich Cornelius Agrippa]] applied the concept of arithmancy to the [[Latin alphabet#Classical Latin alphabet|classical Latin alphabet]] in the 16th century in ''[[Three Books of Occult Philosophy]]''. He mapped the letters as follows (in accordance with the Latin alphabet's place-value at that time):{{sfn|Agrippa|1651|pp=235–236}}

=== Angel numbers ===
'''Angel numbers''', as defined by [[Doreen Virtue]] and Lynnette Brown in 2004, are numbers consisting of [[Repdigit|repeating digits]], such as 111 or 444.{{sfnm|1a1=Virtue|1a2=Brown|1y=2005|2a1=Dickson|2y=2024}} {{As of|2023}}, a number of popular media publications have published articles suggesting that these numbers have numerological significance.{{sfn|Somer|Cardeña|Catelan|Soffer-Dudek|2023}} Doreen Virtue has since renounced the concept of angel numbers in a 2024 interview with ''[[The Cut (New York)|The Cut]]'' declaring that "It’s garbage. I regret it, and I’m sorry that I made them."{{sfn|Dickson|2024}}
