Early theories for the location of Ma-i include locations in
Central Luzon or the
Southern Tagalog regions. and asserted by local historians, suggested
Malolos in
Bulacan as a potential site for Ma-i. For many years, scholars believed that Ma-i was likely to have been on the island of
Mindoro within the municipality of
Bulalacao, as there is an old settlement there named
Mait. However, this has been questioned on the basis of physical evidence and an analysis of Chinese orthography. Recent scholarship casts doubt on this theory, arguing that historical descriptions better match Bay, Laguna (whose name is pronounced either Ba-e[h] or Ba-i), which once occupied a large territory on the eastern coasts of Laguna de Bay. Both sites have names that sound similar to Ma-i. The pre-colonial name of Mindoro was "Ma-it", whereas historical variants of the name of Bay, Laguna include "Bae", "Bai", and "Vahi".
Mindoro as Ma-i Mindoro being equated to Ma-i or Mait was first mentioned in Spanish records, when Chapter 36 of Juan Francisco de San Antonio's
Chronicas de N.S.P. Francisco en las Islas Filipinas, China y Japón 1738 is called
De la Provincia y Isla de Mait o Mindoro ("The Province of the Island of Mait or Mindoro"), showing that the term
Mait and
Mindoro were once interchangeable. From the late 19th century to the early 20th century, scholars such as
Ferdinand Blumentritt and Dr. Fletcher Gardener found out that the Hampangan, otherwise known as the
Hanunoo of southern Mindoro, called the island as
Mait or
Mayit. Toponymic evidence further reinforces this historical continuity. The name Bulacan is etymologically derived from the term for cotton (bulak), a connection mirrored in the historical nomenclature of San Ildefonso (formerly Bulac) and various localities in Bocaue. Similarly, the production of beeswax is reflected in the name of San Miguel de Mayumo, while the recorded trade in betel nuts corresponds to the deeply ingrained cultural practice of betel chewing among the pre-colonial populations of the upper Pampanga River Basin. Furthermore, the mention of sophisticated textiles serves as an index of a well-established, pre-colonial handweaving industry in the provinces of Bulacan and Pampanga. The inclusion of tortoise shells in Wang’s catalog also points toward the ecological significance of the Bataan coastline—a known habitat for sea turtles (pawikan), later evidenced by the Hispanic toponym Tortugas in Balanga. Collectively, these references suggest that the extraction and trade of such marine and terrestrial resources were already systematic and widespread prior to European contact. This early description provides a plausible historical basis for the prevalence of indigo-related toponyms across the Manila Bay littoral, many of which derive from indigenous terms for the indigo plant (Indigofera suffruticosa), such as tayum and nila. Linguistic and geographical evidence further substantiates the antiquity of these dyeing practices. Examples include Patayum (the former name of Barangay San Bartolome in Pampanga), which denotes a site dedicated to indigo dyeing, and Tayuman in Manila, signifying a location for indigo cultivation. Furthermore, the etymology of Maynila (Manila) exemplifies this naming convention; the prefix May- ("to have" or "there is") combined with the root nila ("indigo") suggests that the settlement was historically characterized by the abundance or processing of this natural dye.

Mandarin Relationship with nearby territories The Zhu Fan Zhi mentions a number of territories in its account of Ma-i, saying: Contemporary scholars believe that these are the Baipuyan (Babuyan Islands), Bajinong (Busuanga), Liyin (Lingayen) and Lihan (present day
Malolos City). Malolos is a coastal town and one of the ancient settlement around Manila Bay near Tondo. While the phrase "subordinates" has sometimes been interpreted to mean that these places are territories of Ma-I, Scott clarifies that: ==Ma-i after the Yuan dynasty records==
