figure 
  ax = worldmap([32.5 42],[-125 -114]);
  load coast
  geoshow(ax, lat, long,...
      'DisplayType', 'polygon', 'FaceColor', [.45 .60 .30])
  states = shaperead('usastatelo', 'UseGeoCoords', true);
  faceColors = makesymbolspec('Polygon',...
      {'INDEX', [1 numel(states)], 'FaceColor', polcmap(numel(states))});
  geoshow(ax, states, 'DisplayType', 'polygon', 'SymbolSpec', faceColors)
  Map = xlsread('Locations.xlsx');
Map(:,3) = Cali_info(:,1);
Map(:,4) = Cali_info(:,2);
 geoshow(Map(:,1),Map(:,2), 'DisplayType','Point','Marker','+','Color', 'red','Markersize',12);

Hi Juan,

Unfortunately 'geoshow' function does not have any property that will allow you to use numerical markers on the map. You can instead use 'textm' function to display numerical markers. Refer to the following link to know more about the 'textm' function:

MATLAB Documentation for 'textm' function

You can also refer to the following link which may help you resolve this issue:

I hope the above links will help you to get the desired output. All the best!
